Einstein’s Theory of Relativity

It has been discovered that time and speed are clearly linked: take two synchronized clocks, place one on the ground, the other in an airplane flying around the world.

When they are later set side by side, it appears that the clock placed on the airplane will be running several milliseconds slower than its counterpart. This experiment proves that as speed increases so does the time difference. As such, people residing on earth would age quicker than those traveling through space. This phenomenon of physics is the basis of Einstein’s work and his theory of relativity.
